vnansnsn isnil N mm Patented May 23, 1972 AUTOMATIC STUFFER FOR SLEEPING BAGS BACKGROUND OF THE INVENTION In the past, sleeping bags have been stuffed manually with an insulating batting. Cut-to-length pieces of batting have been manually transferred from a feed conveyor and stuffed by a carriage into an empty sleeping bag ticking in such a fashion that the ticking is closed over the batting. This procedure has been laborious and time-consuming and has presented problems in quality control of the batting due to variations in thickness and negligence in the stuffing operation. Further, the speed has been dependent upon the individual operators expertise which has been greatly subject to variation.

SUMMARY OF THE INVENTION By means of this invention there has been provided a machine for taking a length of sleeping bag batting and automatically stuffing it into an empty sleeping bag ticking. The invention comprises a reciprocal carriage which is elevatable to take or lift the sleeping bag batting from a conveyor in a loading station and carry the batting upon support tines which contact the closed end of a sleeping bag ticking pulled over the open mouth of a funnel or baffle in such a manner that the tines push the ticking inside out to enclose the batting. After the ticking filled with the batting has been carried by the carriage through the funnel and the batting is completely enclosed, the batting-filled ticking is discharged and the carriage which, at this point, hits a reversing limit switch is returned to its initial position where it is stopped by another limit switch.

A stuffing conveyor is employed to transfer a length of a sleeping bag ticking from a main feed conveyor into overlying position over a carriage which as aforementioned is adapted to be elevated to lift the batting off the stuffing conveyor. The stuffing conveyor is provided with special control means which periodically operate the stufiing conveyor at a greatly accelerated rate of speed as compared to the feed conveyor so that the batting is moved rapidly from the feed conveyor to the loading station over the carriage in order to provide ample working space and time in the stufiing operation before the next batting is fed by the feed conveyor to the stuffing conveyor.

Both the reciprocal carriage and the stuffing conveyor are operated by a specially designed timer disc or wheel which is synchronized with the rate of speed of the main feed conveyor. The timer disc is driven by a sprocket chain connected to the main feed conveyor and in its cyclic operation cause a stuffing conveyor cam mounted on the timer disc to energize a stuffing conveyor motor to periodically accelerate the stufiing conveyor. An adjustable cam also carried by the timer disc energizes the carriage motor after the acceleration of the stuffing conveyor has carried the sleeping bag batting into overlying relation.

The automatic machine of this invention is adaptable for stuffing bags of different thickness of batting and different lengths of batting and can simply be adjusted and operated without any special expertise or training. The machine greatly simplifies and increases the speed of stuffing sleeping bags and can be operated by those relatively unskilled in the art.

The above features are objects of this invention and further objects will appear in the detailed description which follows and will be otherwise apparent to those skilled in the art.

DESCRIPTION OF THE INVENTION 22 Which receives a sleeping bag batting 24 shown in dotted lines in FIGS. 1 and 2 from a main feed conveyor 26 which is transferred to stuffing conveyor 28. A reversible carriage 30 rides upon rails 32 supported on the table 22 and is adapted to feed the batting into the mouth of an open funnel or baffle 34 underlying a rack 36 receiving empty sleeping bag tickings 37. A work surface or table 38 is provided at the rear of the main table to receive the enclosed batting and overlying ticking after the stuffing operation. The control of the carriage and the stuffing conveyor is accomplished through a control or timer disc or wheel 40 mounted adjacent the main feed conveyor.

The carriage 30 is best shown in FIGS. 6, 7, 8 and 11. It is more or less U-shaped in form comprising a base 44 mounted upon a journal 46 supporting wheels 48 which ride upon the rails 32 extending longitudinally within the work table. The bed 44 is connected to an upstanding vertical section 50 which supports a plurality of horizontally extending tines 52 which are spaced laterally over the base of the carriage to support the batting as will be further described. The free end of the tines are supported upon an idler roller 54 of the stuffing conveyor in the rest position. Movement of the carriage is effected by a downwardly extending arm 56 which is connected to a sprocket chain 58 extending around an idler sprocket 60 connected to a forward leg of the table as best shown in FIG. 6 and a powered sprocket wheel 62 connected to a drive shaft 64 of a motor 66 connected to a brace at the rear portion of the work table as best shown in FIGS. 7 and 13. A contact stud 68 is also connected to the bottom of the carriage which is adapted to contact a stop limit switch 70 for stopping the carriage motor and a reversing limit switch 72 connected to a brace at the rear of the table as best shown in FIG. 12.

The forward portion of the rails 32 are provided with detents 74 as best shown in FIG. 6 in which the carriage wheels are received so as to lower the carriage out of contacting rela tion with the batting. As the carriage is advanced upon its operation, it will be understood that the carriage is raised upon the rails 32 into batting-carrying relation to lift it ofithe stuffing conveyor as will be further described.

The stufiing conveyor 28 is comprised of a plurality of laterally spaced conveyor belts 80 as best shown in the plan view of FIG. I. The conveyor belts are so spaced as to receive the tines 52 of the carriage when the carriage is elevated in such a fashion that the tines pass through the spaces between the conveyor belts 80. The stuffing conveyor is driven by a drive shaft 82 and the conveyor is guided around idler rollers 84 at the forward end of the table roller 54 at the rear end of the table which further acts to support the free ends of the tines of the carriage, roller 88 at the forward end of the table, and tension rollers 90 and 92, likewise mounted at the very forward portion of the table as best shown in FIG. 2.

Normal powering of the stuffing conveyor is effected at the same rate of speed as the main feed conveyor by a sprocket chain 86 connected through a conventional overriding clutch 89 to a drive shaft 90 for the conveyor roller 82. The sprocket chain 86 is connected to a sprocket wheel 92 driven by the main feed conveyor. The main feed conveyor has an extension conveyor 94 for transferring the batting to the stuffing conveyor which is powered by a roller 96 and a roller 98. The roller 98 is driven by a main feed conveyor sprocket chain 100 as best shown in FIGS. 1 and 8.

The aforementioned clutch 89 on the drive roller 82 of the stuffing conveyor is for the purpose of permitting stuffing conveyor motor 102 to override the sprocket chain connection to the main feed conveyor system by a faster drive shaft speed and provides for the great acceleration of the stuffing conveyor to several times the rate of speed of the main feed conveyor. It will be understood that by the control system to be described, the stuffing conveyor motor 102 operates only intermittently to separate a cut length of batting from the batting of the main feed conveyor and convey it to an overlying relationship over the reversing carriage for the stuffing operation. The stuffing conveyor motor 102 has a drive shaft 104 which is connected to the drive shaft 90 of the stuffing conveyor drive roller by sprocket chain 106 as best shown in FIGS. 1 and 4.

The main feed conveyor is of conventional construction and is best shown in FIGS. 1, 4 and 8. It is comprised of a conveyor belt 110 which receives a continuous ribbon of batting and terminates over the conveyor roller 1 12 which is driven by the sprocket chain 100. The main feed conveyor also drives the conveyor roller 96 through a sprocket chain connection between rollers 96 and 98 as shown in FIG. 1 as previously described in such a fashion that the extension conveyor 94 serves to transfer the batting from the main conveyor 1 and feed it to the stuffing conveyor. It will be understood that the continuous ribbon of batting is adapted to be cut by conventional means such as the rotary cutter 113 shown in dotted lines in FIG. 8 which has a blade 114 which periodically cuts the batting at desired lengths appropriate to that required for stuffing different sized sleeping bags.

The funnel 34 is best shown in FIGS. 1, 2, 3 and 7. It is comprised of a pair of oppositely mounted U-shaped members 120 which are mounted on a forwardly extending section 121 of the working table 38. This structure provides an open area 122 within which the batting and the supporting tines 52 of the carriage are adapted to be fed. The funnel 34 is adapted to receive an open-ended bag ticking 37 within which the batting is to be stuffed. The ticking is gathered over the funnel in the fashion as shown in FIG. 7 such that the closed end 124 covers the open mouths 126 of the funnel members. The contact of the ends of the tines 52 of the carriage with the closed end 124 will then turn the sleeping bag inside out and carry it within the interior of the funnel with the batting covered by the ticking which will be best understood by reference to FIG. 7.

The control mechanism for the carriage in the stufiing conveyor which comprises as its integral component the timer disc 40 is best shown in FIGS. 1, 2, 5 and 8. The timer wheel 40 is connected to a sprocket wheel 128 which is driven by a sprocket chain 129 connected to the main feed conveyor. A stuffing conveyor starter cam 130 is provided by a raised portion of the periphery of the wheel and as best shown in FIG. 10 is adapted to engage at the proper rotational position a contact switch 132 which is adapted to energize the stufiing conveyor motor 102. The cam 130 has a circumferential surface 134 which provides for a period of dwell of the switch 132 upon its surface for a short period of operation of the stuffing conveyor motor to transfer the batting from the main feed conveyor to the loading station overlying the carriage. The timer disc 40 is connected to the sprocket wheel 128 by bolts 136.

The timer wheel 40 further carries an adjustable cam 138 mounted on the outside face of the timer disc as best shown in FIG. 8. The cam 138 is provided with a slot 140 and an adjustment bolt 142 which fits through the slot and is connected to the timer disc in order that the cam 138 can be adjusted either closer to or further away from the stuffing conveyor cam 130 to accommodate different lengths of batting. The cam 138 has an extended arcuate surface 143 which is concentric with the timer wheel 40 and the sprocket wheel 128 in order that the carriage can be operated for the period of time necessary for its complete cycle. The cam 138 operates the carriage motor 66 through a limit switch 144, which energizes the carriage motor 66. This motor has a reversible field in order that the reversing limit switch 72 can reverse the motor and return the carriage to its rest position.

OPERATION In the operation of the automatic stuffing machine, an operator will first of all insert a ticking inside out over the fun nel 34 in the fashion shown in FIG. 7. This is the only operation required by an operator until the batting is inserted by the automatic stuffing operation into the sleeping bag ticking and discharged at the discharge station 38 at the rear of the worktable.

The operation of the automatic stuffing machine is started with the feed of batting by the main conveyor and the cut of the batting to the desired length by the cutter 112 to present the selected length of batting to the extension conveyor 94. This conveyor, in turn, transfers the batting which is shown in dotted lines in FIG. 1 to the stuffing conveyor 28. As the stuffing conveyor operates for the major portion of the cycle at the same speed as the main feed conveyor, the batting is carried onto the stufiing conveyor at which time the cam 130 of the timer disc 40 operates the contact switch 132 which in turn causes the operation of the stufiing conveyor motor 102. The operation of motor 102 causes the increase of speed of the driven conveyor roller 82 to override through clutch 89 the connection to the sprocket chain to the main feed conveyor and greatly increases the rate of speed of the stuffing conveyor to rapidly move the batting to the position shown in dotted lines in FIG. 1 where it overlies the carriage in the loading station. At the completion of this stufiing conveyor acceleration, the cam 130 rides out of contact with the contact switch 132 and resumption of the movement of the stuffing conveyor at the normal rate of speed is continued.

The carriage operating cam 138 through the counterclockwise rotation of the timer disc 40 now causes the operation of contact switch 144 to energize the carriage motor 66 and drive the sprocket chain 58 which, through the connection of the arm 56, causes the movement of the carriage out of the detent 74 and the elevation into supporting relation with the batting. The tines 52 will then lift the batting out of contact with the stuffing conveyor and advance over the idler roller 54. The ends of the tines contact the closed end 124 of the ticking and the batting is moved into the interior of the funnel 34 in such fashion that the ticking is turned inside out to enclose the batting. The batting now enclosed by the sleeping bag ticking moves through the funnel and is discharged and pulled off by an operator at the discharge station 38 to complete the stuffing operation.

The carriage at the completion of its forward movement contacts the reversing limit switch 72 shown in FIG. 12 which reverses the reversible motor 66 to return the carriage to its forward position where contact stud 68 at the bottom of the carriage contacts the stop limit switch 70 to stop the carriage in the rest position with the wheels in the detent 74 of the support rails.

The aforementioned operation completes the cycle until the timer disc 40 again through the stuffing conveyor cam 130 causes the operation of switch 132 to start a new cycle, and the operation is repeated in the aforementioned manner.

The stuffing operation provides a ticking completely encasing the batting which is then removed from the working .area 38. This assembly is then finished in conventional fashion.

The final sleeping bag 150, after stitching of the open end and doubling over of the sleeping bag along the longitudinal axis and the addition of a conventional zipper 152 along the bottom and the side, is shown in FIG. 15.
